PBP BIT variables in MPLAB:

Bit variables in PBP are created as aliases to individual bits within a byte variable created to hold them. MPLAB won't display the bit aliases, but it will display the byte container variable. The problem is, you don't know the name of the container variable or the placement of the specific bits without digging into the .ASM file.

One solution is to create your own container variable and bit aliases. This won't make the bit names show in MPLAB, but it will allow you to show the container variable. You'll know which bits are which, because you defined their locations in the first place. There's no performance penalty using this method, because it's exactly what PBP would do if you declared bit variables. There are, in fact, advantages... like the ability to initialize multiple bit variables with a single command.

<code>
mybits VAR BYTE

bitflag0 VAR mybits.0
bitflag1 VAR mybits.1
bitflag2 VAR mybits.2
</code>

Now the variable "_mybits" will be available in the MPLAB watch window, and you'll know how the individual bits in the variable relate to your program.

Excellent Charles! I fully intend to use this technique.

Nice one.
